摘要： Data having a small amount of data, such as still image data, is transmitted by using asynchronous packets. A source apparatus writes data which can be selected from a data source block into a data descriptor within a memory. Then, the source apparatus transmits the data read from the data descriptor to a receiver apparatus by using asynchronous packets. The receiver apparatus can also write data which can be selected from the data source block into a data descriptor within a memory.

摘要： To control the audio-recording mode of a video tape recorder used in a communication system, a plurality of pieces of equipment are connected to each other by communication-control buses for carrying out communication among them. Data "71h" set in an OPC (operation-code) field of a command specifying an audio-recording mode of a video tape recorder indicates an audio-recording mode. RM1 to RM4 sub-fields set in an OPR1 (operand) field indicate whether audio recording is to be carried out on Channels 1 to 4 respectively. SF1 to SF4 sub-fields of OPR2 and OPR3 fields indicate the sampling frequencies of Channels 1 to 4 respectively. NA1 to NA4 sub-fields of the OPR2 and OPR3 fields indicate whether one-channel audio recording, two-channel audio recording or 20 bit audio recording is to be carried out on Channels 1 to 4 respectively. Therefore, by transmitting a control signal conveying such a command, other equipment can specify the audio-recording mode of the VTR.

摘要： An Open Descriptor demanding an access right is transmitted from a personal computer to a DVD player. In response to this demand, the DVD player transmits either an Accept response or a Reject response. Upon receiving the Accept response, the personal computer transmits a Write Descriptor. The Write Descriptor indicates an instruction that data (da) having a data length (le) is written (AuthDe) into an address (Add) of a sender (SD). Upon receiving this Write Descriptor, the DVD player transmits the Accept Write Descriptor indicating that the writing instruction has been accepted. Thus, in an authentication protocol, data is transmitted in accordance with the size of the buffer for use in an electronic machine.

摘要： A method and apparatus for controlling communication between components connected to a bus. All equipment manufacturers may use every application available on each connected apparatus by using a unique vendor command in accordance with the IEEE-1394 standard. A controller, when accepting a target key code, calculates an application key code based on a cipher function and a target key code therefor. Then, an opening command is transmitted for the application associated with the application key code. The target apparatus, when accepting the opening command, decodes the target key code in the command. If the result of decoding is equal with the target key code of its own, an application is placed in an executable open state.

摘要： The encoded data outputted from a DVD player 1 are outputted to and decoded in the decoders 4-1 to 4-3 of digital television receivers 3-1 to 3-3 through an AV bus 5 comprising the IEEE 1394. When a command for changing a system parameter is inputted to any one of the decoders 4-1 to 4-3, the command corresponding to the change is supplied to the DVD player 1 through the AV bus 5. The DVD player 1 changes the system parameter in response to the command and outputs the system parameter to the respective decoders 4-1 to 4-3 through the AV bus 5. Thereby, the system parameter is changed not only in the DVD player but also in other components.

摘要： A transmitting system consisting of a control apparatus and a target apparatus connected mutually via an IEEE1394 bus wherein unitary data having an isochronous gap for transmission of audio main data and an asynchronous gap for transfer of command data are transmitted between the control apparatus and the target apparatus via the bus. The control apparatus includes a unit for sending an identifier to identify the target apparatus by the use of the asynchronous gap, and also a command to request transfer of a signal level from the target apparatus. The target apparatus includes a unit for receiving the identifier from the sending unit of the control apparatus via the IEEE1394 bus and also the command to request transfer of the signal level of the target apparatus; and a unit for sending an audio signal level in response to the signal-level transfer request command received by the receiving unit. In this system, an output level can be set in and read out from the target apparatus by the control apparatus.
